"An updated flac package to correct a security issue is now available
for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

FLAC is a Free Lossless Audio Codec. The flac package consists of a
FLAC encoder and decoder in library form, a program to encode and
decode FLAC files, a metadata editor for FLAC files and input plugins
for various music players.

A security flaw was found in the way flac processed audio data. An
attacker could create a carefully crafted FLAC audio file in such a
way that it could cause an application linked with flac libraries to
crash or execute arbitrary code when it was opened. (CVE-2007-4619)

Users of flac are advised to upgrade to this updated package, which
contains a backported patch that resolves this issue."
